480 is the least common multiple
120*4=480
160*3=480
there is no number smaller than 480 that is both a multiple of 120 and 160
therefore the least common multiple is 480

160 / 120 = 1 + reminder
160 = 120 * 1 + 40
120 / 40 = 3
120 = 40 * 3 + 0
Greatest common divider GCD(160,120) = 40
LCM(a,b) = ab/GCD(ab) = 120 * 160 / 40 = 480

your Q makes no sense..., multiples are 480, 960, 1440... none less common by any definition I know
